Howdy, Shmiterude.<br /><br />Welcome to iboats. <br /><br />Give us the model number so we can determine the exact year.<br /><br />You will need a Service Manual. After we get it identified you can Google up Ken Cook for a reprint of the original.<br /><br />One of your magnetos is probably faulty. Most likely culprit is dirty points, but those engines are known to have coil failures, too.<br /><br />Let us know the model number, and good luck.

It is most likely a cracked coil. Take off the flywheel and inspect the coil and clean/regap the points

I had this problem with my 1962 Sportwin 10hp. It was a failed condenser. Changed that, now sparks x2!!!

Fortunately, parts are cheap. Fact is you can replace the entire igntion system for around $60.<br />The service manual is good advice. It will save a lot of trouble later. But if you want to see what's involved check out Tom Travis' 5.5hp webpage:<br /> Click here.

That is $60 unless you purchase in our area, then read $260 for parts, special order, etc..

Ah yes, Dryden. I was presuming this was from the US. Back when I was getting parts from the 'States, it ended up being around $100CAD all told if you used Fedex instead of UPS. Locally the coils go for around $20 online or about $45 each from the dealer. The points & condensors kit is around the same.
